'TIME-Fiume MEGHANISM FOR SHELLSTQRPEUUES, sb-o..

SPECIFICATION forming To all whom it may concern:

Be it knownthat 1, MYRoN CoLoNEY, of and State of Missouri, have invented a Time-Firing Mechanism for Shells, Torpedoes, and Blasting- Cartridges, of which the following is a specication. My apparatus consists, essentially, of a train of gearing driven by a spring and connected with a suitable governor, preferably a fan, and witha Spring firing-pin, which is released by the time mechanism after a period which may be varied by the adjustment of a rotary de- -tent carried by the Said time mechanism.

In the accompanying drawings, Figure 1 iS a side elevation of my time mechanism as adapted for use in explosive projectiles. Fig. 2 is a rear view. Fig. 3 is a transverse section on the line 3 3, looking forward. Fig. 4 is atransverse section on the line 4,4, looking backward. Fig. .5 isa transverse section on the iine 5 5, looking forward. Fig. 6 is a longitudinal sectional diagram or flat projection of the mechanism on the broken line 6 6, Fig. 4...

The object oi' this piece of mechanism is to effect and regulate the explosion `of gunpowder, gun-cotton, and similar detonating` compounds, whether they be used inland or naval warfare or in the industrial arts of blasting or mining. It is especially adapted to the eX- plosion oi' bomb-shells and torpedoes. V

Among its important advantages are the accuracy and simplicity with which it may be timed, and the rapidity in which itmay be adjusted and set in motion ready for action; Safety from all danger of accident by premature explosion when the use of the mechanism is not needed, andthe certainty that it will do its duty at the time required.

yBy Simply .removing a Small plug,`(which` protectsfrom tampering) adjusting the movement to the time required, as indicated on a 'dial on therear end, drawing out a small wire which sets the mechanism in motion, and replacing the plug again, the apparatus is set in action, and the explosion will take place at the time required.

The whole. operation, which is the work. of

its parts.

a few seconds, is done with a small wrench, which the operator holds in his hand.

The mechanism maybe constructed so as to run for several hours, or an'iexplosiou can be effected immediately, as required. lt can be reduced in size to the diameter of -a ladys watch by about three inches in length, land by reason oi' its great strength and lightness and ,the peculiarity of its construction it can be used in the smallest-size bomb-shells.

The following is a detailed description. of l The connections will be understood by reference to the at longitudinal sectional diagram., Fig. 6, in addition to the transverse sections.

Gis 'the main arbor, wni'ch is operated by the large eonvolute spring A, and which is wound upby a wrench placedupon the outer end, a. The .Spring has nearly the whole diameter of the movement to operate in, deduct` ing only the cartridge-holders and the pillars b b from the entire diameter. The outer end oi' the spring is secured by one of thepillars, or by a special screw, as shown at d in Fig. 5, and the inner end is held by a pin, which passes transversely through through a holeiin the spring.

e is a ratchet, which operates the main wheel f. g isa washer, which is heldin position by the end of the hearing on the arbor 0 being riveted over-onthe outside of the washer at i. The wheel f imparts Inotion to the pinion h, and thence, through the train of wheels and The train, in the present instance, is geared up in the proportion of twenty-two thousand eight hundred on the ily-shaft to one on the main varbor O. The iiymakes in all one hundredand thirty-six thousand eight hundred revolutions to one of the tiring-arbor S, as the main arbor O is geared with the firing-arbor S in the proportion of six to one. In other words, when the movement is set so as to make the greatest length of time, as it is at present geared, the ily-arbor must revolve one hundred and thirty-six thousand eight hundred timesv before the cartridge is fired. The ily passes through the'plate c3 in order that it may'havethe greatest possible 4size in the least Space. f

every completerevolution, and at the same Y peint, when the movement Yis setV to run its explosion sought for is thereby attained- The:

greatest length of time, vturning the tiring-'pin toward the firing-point from the end q, or, in other words, adjusting it, has the ei'ect ofreducin'gthe' time it will take the movement to bring the pin to the firing-point 5 and the time necessary to 'make the entire revolution being already known, the amount of' time thus cut otf is deducted, and the time ofthe explo Asion thereby determined. It must not be inferrcd, however, that any mathematical calculation is-necessary on the part ot the operator, as h'e simply' turns the shaft q .until the index points to the proper figure on the dial, or he turns-a little pointer on his wrench to a secret ligure, which to himindicates the time of the explosion, then removes his wrench, and all is ready.

The stud 1"- draws the trigger s' (see Figs. 3

and 6) 'by operating on the 'incline a", vwhich y liberates-tln hammer -t at c.

` The hammer thus.liberated is thrown forcibly by the spiral spring a uponthe cartridge fw, and causes its explosion, which, in turn, communicates re with the compound. to be exploded, and the hammer is retracted or cocked by means of a thumb-piece, 7c. lThe surface p* of trigger s, coming in lcontact with the peripherybf the vfiring-Wheel p, prevents the liberation or" the hammer at u until the recess ,c in the'firingwheel p comes opposite to pX,..hereby insuring perfect 'safety from accident by premature explosion, as the hammer is .by this arrangement locked at u by the trigger e.

On the other hand, when the recess p comes opposite to eend px of trigger s the trigger-pin r, operatedby the spring A through the wheel Z, presse/s against the incline at cf, which Vdraws'the trigger, by a positive motion, away /from the hammer at u and i nto the recess pf,

The-plates c c2 c3 c4 are held togetherby the screws b bv, which screw into the lower plate, and having the heads countersunk into the np per plate. The threaded ends of the screws are finally riveted on the outside, thereby combining a rivet with a screw.

The plates are kept apart and in position by pieces of brass tubing, cut the prolrwiler e ubing andn the screws togetherrmakethe'pilf ars.

lets, or seats for the'wheels and the pivots are turned and cut in one piece of steel. The wheels are also keyed andfriveted on the collets, therebypreventing any stepping of` wheels or shifting on arbors, and precluding all possibility of a premature explosion-an event which might occur with the use of the yordinary clock machinery.

' The clicks or detents are kept in position by*tempered-steel' springs fastened in such a manner as to remove all liability of shifting. The principle of the iiy is used because it is the simplest, most direct, and posi tive of' any 'regulator that can be selected, friction being the only element necessary to overcome.

- While escapements are more accurate and better adapted to time-pieces than the ty, the

fact thatl they have dead-centers, recil'irocat- 'ing motion, and must be-suspendcd, so very delicately renders them useless for such a piece of mechanism as this.

r.Ehe Whole movement is constructed with the design of having the greatest strength with the least weight andthe largest machinery in the least pcssi'olespace, `and oi" standing a great shock or concussion without derangement.
